Description

  The present invention relates to a technique in which a game device including a touch panel display unit controls the progress of a game.

  In recent years, mobile phones including a touch panel display unit have become widespread (for example, i-phone (registered trademark)). In this mobile phone, the user can perform all operations by touching the touch panel. Therefore, it is not necessary to provide physical buttons such as a numeric keypad on the mobile phone, and a simple appearance is realized. In addition, this mobile phone is basically operated with a finger on the touch panel or lightly pressed with a finger, that is, with the addition of a tracing operation in addition to a pressing operation, the pressing operation is fundamental. Compared to the conventional mobile phone, a novel user interface is realized.

  And a mobile phone provided with this touch panel type display unit can play a game like a conventional mobile phone, and development of a game utilizing this novel user interface attracts attention.

  By the way, as a conventional game apparatus, there is known a game apparatus that includes a touch panel display unit and can move a character in a game space by moving the touch pen on the display screen.

  For example, Patent Document 1 discloses a baseball game in which a defensive character is moved by an operation of a touch pen and the defensive character catches a ball returned by the batter character.

Japanese Patent No. 3822217

  However, since the game of Patent Document 1 is premised on the use of a touch pen, the features of the user interface of a mobile phone provided with a touch panel display unit based on finger operation cannot be fully utilized. For example, the operation of the touch pen that makes contact with the screen simply moves the operation target character (defense character) to the target position with its posture and shape, and the operation is relatively simple. It does not relate to the movement or movement of the character itself. The applicant pays attention to this point, and can manipulate complex and subtle movements of the character itself by operating the fingers, and the evaluation and victory or defeat with the opponent are determined based on the movement state and movement result of the character by the skill of the operation I thought that it would be possible to realize an uninteresting game by building such a system.

  An object of the present invention is to realize a game in which a user interface of a mobile terminal having a touch panel display unit is utilized to operate the movement and movement of the character itself, and the movement speed, the movement distance, and the like are changed based on the movement. It is to provide a game control program or the like that can be used.

  (1) A game control program according to an aspect of the present invention is a game control program that causes a game device including a touch panel display unit to control the progress of a game. The game includes a predetermined character in a game space. Receiving means for accepting an operation input from a player that touches and moves a finger so that a predetermined trajectory is repeated on the display screen of the display unit, and a predetermined character is displayed on the display unit, Based on the operation input accepted by the accepting means, the display control means for changing the display mode of the character, and based on the operation input accepted by the accepting means, the player actually performs the display on the display screen of the display unit. A trajectory length calculating means for calculating the length of the trajectory moved in contact with the trajectory, and the trajectory length calculating means. A moving distance calculating means for calculating the moving distance of the character in the game space according to the length of the trajectory, and a movement for moving the character in the game space according to the moving distance calculated by the moving distance calculating means. The game device is made to function as means.

  A game device according to another aspect of the present invention is a game device including a touch panel type display unit, and the game moves a predetermined character in the game space, On the display screen, a receiving unit that receives an operation input from a player that moves a finger so that a predetermined trajectory is repeated, and a predetermined character is displayed on the display unit, and the operation input received by the receiving unit Based on the display control means for changing the display mode of the character, and the length of the trajectory that the player actually moved on the display screen of the display unit based on the operation input received by the receiving means. The trajectory length calculating means to calculate and the length of the trajectory calculated by the trajectory length calculating means in accordance with the character length in the game space. And moving distance calculating means for calculating a moving distance of Kuta, according to the movement distance calculated by the moving distance calculating means and to function game device as a moving means for moving the character in the game space.

  A game control method according to another aspect of the present invention is a game control method in which a game device including a touch panel display unit controls the progress of a game, and the game is a predetermined character in the game space. An accepting step for accepting an operation input from a player that moves a finger so that a predetermined trajectory is repeated on the display screen of the display unit, and the game device comprises: A display control step of displaying a predetermined character on the display unit and changing a display mode of the character based on an operation input received by the receiving step; and an operation received by the game device by the receiving step. Based on the input, the length of the trajectory that the player actually touched and moved on the display screen of the display unit. A trajectory length calculating step for calculating the character, a moving distance calculating step in which the game device calculates a moving distance of the character in the game space according to the length of the trajectory calculated in the trajectory length calculating step, The game device includes a moving step of moving the character in the game space according to the moving distance calculated in the moving distance calculating step.

  According to these configurations, when the player performs an operation of repeatedly touching and moving (tracing) a predetermined trajectory with a finger, the display mode of the character displayed on the display unit changes according to the operation. When the player performs an operation of tracing a predetermined trajectory, a trajectory length that is the length of the trajectory that the player actually traces the display unit is calculated.

  Based on the calculated trajectory length, the moving distance of the character in the game space is calculated. In the game space, the character is moved according to the moving distance.

  That is, the player can increase the moving speed of the character as the trajectory length when tracing a predetermined trajectory is increased, that is, as the distance that the finger is moved in contact with the display unit is increased.

  Therefore, the player is required to secure a distance for moving the finger in contact and at the same time increase the number of times of tracing the trajectory, which makes the game interesting.

  In a conventional swimming game or athletics game, there is no operation of tracing the display screen, so that such a requirement is not imposed on the player. Further, since the game shown in Patent Document 1 moves a defensive character to a target position with a touch pen and does not repeat a predetermined trajectory, such a requirement is not imposed on the player.

  Therefore, according to the above configuration, the character can be moved by performing an operation of repeatedly tracing the display unit with a finger, and by utilizing the user interface of the mobile terminal provided with the touch panel type display unit, It is possible to realize a game in which an operation is operated and a moving speed, a moving distance, etc. are changed based on the operation.

  (2) The character imitates a human, and the display control means moves the player's finger around the trajectory once in a circle, and moves the character's left arm, right arm, left leg, and right It is preferable to change the display mode of the character so that at least one of the legs moves. Note that “one round” here refers to a circular trajectory until the finger touches and moves from the starting point where the finger touches the display unit to return to the starting point, and the finger moves from the starting point where the finger touches the display unit. It also includes a case where the section is moved to the end point until the end point where the finger is moved away from the display unit at a predetermined point.

  According to this configuration, when the player performs an operation of tracing a predetermined trajectory with a finger, at least one of the left arm, the right arm, the left leg, and the right leg of the character is interlocked with the tracing operation every time it is traced. The display mode of the character is changed so that one is operated.

  Thus, the player can individually move a part of the character's body (for example, an arm) by performing an operation on the display screen, and moves the body as if by directly moving the character's arm ( It is possible to provide a game having an interest that is not present in the past.

  (3) The trajectory length calculating means calculates a unit trajectory length that is the length of a trajectory that the player actually moves the display unit in contact with the player every time the player traces the trajectory. The moving distance calculating means calculates a unit moving distance, which is a moving distance per action of the character in the game space, based on the unit locus length calculated by the locus length calculating means. It is preferable to move the character along a predetermined reference direction in the game space by the unit movement distance calculated by the movement distance calculation means.

  According to this configuration, each time the player performs an operation of tracing the predetermined trajectory once, a unit trajectory length that is the length of the trajectory actually traced by the player on the display unit is calculated.

  Then, based on the calculated unit locus length, a unit movement distance that is a movement distance per action of the character in the game space is calculated. Then, the character is moved by the unit movement distance in the game space.

  That is, as the number of times the player traces the predetermined trajectory increases, the number of times the unit movement distance is calculated increases, and the character movement speed can be increased accordingly.

  On the other hand, the player increases the trajectory length when the predetermined trajectory is traced once, that is, the longer the distance that the finger is moved in contact with the display unit, the longer the unit movement distance becomes. Can be faster.

  (4) The trajectory includes a pair of left and right left trajectories and a right trajectory, and the unit trajectory length includes a left unit trajectory length corresponding to the left trajectory and a right unit trajectory length corresponding to the right trajectory, The accepting means accepts an operation input for moving the left trajectory in contact with a left finger and an operation input for moving the right trajectory in contact with a right finger, and the trajectory length calculating means allows the player to make one round of the left trajectory. The left unit trajectory length is calculated each time the contact is moved, and the right unit trajectory length is calculated each time the player moves the right trajectory once in a contact manner, and the moving distance calculation means includes the left unit trajectory length and the left unit trajectory length As the difference from the right unit trajectory length increases, it is preferable to calculate a distance decrease value whose value increases, and to correct the unit movement distance by subtracting the distance decrease value from the unit movement distance.

  According to this configuration, as the difference between the left unit trajectory length and the right unit trajectory length increases, that is, the contact moving distance when the display unit is traced with the left finger and the contact when the display unit is traced with the right finger. As the balance with the movement distance becomes worse, the unit movement distance is decreased. In other words, the worse the balance between the left and right, the slower the progression of the character. Therefore, the player is required to move the left and right fingers in a balanced manner, which can further increase the fun of the game.

  (5) In the case where the difference between the left unit trajectory length and the right unit trajectory length is greater than a predetermined value, the display control means determines that if the left unit trajectory length is shorter than the right unit trajectory length, Is tilted to the left from a predetermined reference direction, and when the right unit trajectory length is shorter than the left unit trajectory length, the character is tilted to the right from the reference direction, and the character is moved in the reference direction. It is preferable to display an afterimage.

  According to this configuration, when the difference between the left unit trajectory length and the right unit trajectory length is large, it is possible to notify the player that the traveling direction of the character is deviated from the reference direction. Thereby, the player can easily visually recognize the imbalance of the operation of the left and right fingers, and can correct the operation.

  (6) The receiving unit alternately receives an operation input for moving the left trajectory in contact with a left finger and an operation input for moving the right trajectory in contact with a right finger, and the moving distance calculating unit The unit movement distance is calculated every time a trajectory length is calculated, and the unit movement distance is calculated every time the right unit trajectory length is calculated, and the current left unit trajectory length and the previous right unit trajectory length are calculated. The distance decrease value is calculated so that the value increases as the difference between the current right unit trajectory length and the previous left unit trajectory length increases, and the distance decrease value is subtracted from the current unit travel distance. Thus, it is preferable to correct the current unit movement distance.

  This configuration corresponds to, for example, character operations such as crawl in a swimming game, 100 m running in an athletics game, track competition, and heel advance in the game, and the player traces to move left and right fingers alternately. By performing the operation, the character can be moved in the traveling direction. At this time, if the balance between the movements of the left and right fingers is bad, the unit movement distance is calculated so that the unit movement distance of the character is reduced.

  (7) The receiving unit simultaneously receives an operation input for moving the left trajectory in contact with a left finger and an operation input for moving the right trajectory in contact with a right finger, and the moving distance calculating unit is configured to detect the left unit trajectory. The unit travel distance is calculated every time the length and the right unit trajectory length are calculated, and the distance decrease value is increased so that the value increases as the difference between the left unit trajectory length and the right unit trajectory length increases. Preferably, the unit movement distance is corrected by subtracting the distance decrease value from the unit movement distance.

  This configuration corresponds to character operations such as breaststroke in the swimming game, butterfly, and rabbit jump in the game, for example, and the player can move the character by moving the left and right fingers symmetrically. it can. At this time, if the balance between the movements of the left and right fingers is bad, the unit movement distance is calculated so that the unit movement distance of the character is reduced.

  (8) The left trajectory and the right trajectory have a closed loop shape, and the movement distance calculation means causes the left and right finger trajectory shapes that the player has actually moved the display unit to contact with each other deviate from the closed loop shape. In this case, it is preferable to correct the unit moving distance so that the unit moving distance decreases.

  This configuration corresponds to, for example, a breaststroke in a swimming game. When the shape of the trajectory of the left and right fingers deviates from the target closed loop shape, the unit movement distance is calculated so that the value decreases. Therefore, the player is required to move the left and right fingers so that the shape of the finger trajectory becomes a target closed loop shape. Thereby, the interest of the game can be further increased.

  (9) The closed-loop shape includes a straight line and an arc connecting both ends of the straight line, and the moving distance calculating means is a position of a finger on the display unit when the player starts an operation of moving the arc in contact with each other. When an arc start point is detected, an arc determination point is set at a predetermined position on the display unit with reference to the arc start point, and the arc trajectory moved by the player passes outside the arc determination point It is preferable to determine that the shape of the locus does not deviate from the closed loop shape.

  This configuration corresponds to a breaststroke in a swimming game, for example. Then, an arc start point which is the position of the finger on the display unit when the player starts an operation of tracing the arc is detected, and an arc determination point is set at a predetermined position on the display unit with reference to the arc start point. When the arc trajectory actually traced by the player passes outside the arc determination point, it is determined that the arc shape is not deviated from the closed loop.

  Therefore, whether or not the shape of the trajectory has deviated from the closed loop is determined depending on whether or not the arc trajectory actually traced by the player has passed outside the arc determination point, and the processing can be simplified. .

  (10) The left trajectory and the right trajectory are line segments, and the accepting unit moves the left finger from the display screen when an operation for moving the left trajectory in contact with the left finger reaches the end of the line segment. When the operation input to release and return to the tip of the line segment and the operation to move the right trajectory with the right finger reach the end of the line segment, the right finger is moved away from the display screen and moved to the tip of the line segment. The movement distance calculation means receives the return operation input, and the moving distance calculation means detects the timing when the left finger is returned to the tip of the line segment and touches the display screen, and the right finger is returned to the tip of the line segment. Preferably, the unit movement distance is corrected so that the unit movement distance decreases when the timing of contact on the display screen deviates.

  This configuration corresponds to, for example, a butterfly in a swimming game, and when the player reaches the end of the line segment that becomes the trajectory, the player separates the left and right fingers from the display screen and ends the line segment that becomes the trajectory. The character is moved by repeating the operation of returning to. At this time, if the timing when the left and right fingers are returned to the tip, that is, the timing when the left and right fingers touch the display screen is deviated, the unit movement distance becomes shorter as the deviation becomes larger.

  Therefore, the player is required to move the left and right fingers in a balanced manner, and the game can be more interesting.

  (11) The game is a swimming game, and an operation input for moving the left finger in contact on the display screen and an operation input for moving the right finger in contact on the display screen are alternately received by the receiving means. Determines that the character is swimming in a crawl, and when the operation input is received by the accepting means so that the left finger and the right finger are not moved away from the display screen, the left finger and the right finger When the operation means that touches the display screen almost simultaneously is received by the accepting means after the player has left the display screen almost simultaneously, the game device is used as a judging means for judging that the player is swimming the butterfly on the character. Further functioning is preferable.

  According to this configuration, the player can change the finger movement pattern to allow the character to swim in one of the crawl, breaststroke, and butterfly, increasing the degree of freedom of manipulating the character, and increasing the fun of the game. Can be made.

  (12) If the determination means determines that the character is swimming in the crawl, the display control means displays the character as if it is swimming in the crawl, and the determination means causes the character to swim If it is determined that the character is swimming in a breaststroke, the character is displayed as butterfly when the determination means determines that the character is swimming in a butterfly. It is preferable to display as if swimming.

  According to this configuration, since the character is displayed in a display mode corresponding to the type of swimming, the player can quickly recognize the current swimming of the character.

  According to the present invention, by utilizing the user interface of a portable terminal having a touch panel type display unit, it is possible to operate complicated and subtle movements of the character itself by the operation of the player's finger, and the movement state of the character by the skill of the operation By building a system in which evaluation based on the result of movement and the result of the movement and the victory or defeat with the opponent are determined, it is possible to realize an uninteresting game.

  FIG. 1 is a block diagram of a mobile phone when the game device according to the embodiment of the present invention is applied to the mobile phone. This mobile phone is a mobile phone including a touch panel type display unit.

  For example, a packet communication network provided by a mobile communication carrier is used as the mobile phone network to which the mobile phone is connected, and the mobile phone is a base station of the mobile communication operator with which each user has a contract. Connected through.

  Note that the game device is not limited to a mobile phone, and a mobile terminal having a communication function such as PHS (Personal Handy phone System), PDA (Personal Data Assistance) may be adopted.

  In the following description, a swimming game in which the player operates the character of the swimmer and competes for the time until the goal is reached is adopted as the game.

  The mobile phone shown in FIG. 1 includes an operation display unit 10, a communication unit 20, an audio output unit 30, a control unit 40, and a storage unit 50. The operation display unit 10 includes, for example, a liquid crystal panel and a touch pad attached on the display surface of the liquid crystal panel.

  As the touch pad, for example, a capacitive type or a resistive film type is adopted, and a position signal which is two-dimensional data indicating a position on the display screen touched by the player is output to the control unit 40. The control unit 40 recognizes the position on the display screen touched by the player from the position signal.

  As the liquid crystal panel, for example, a liquid crystal panel such as TFT (Thin Film Transistor) or STN (Super Twisted Nematic) is used, and for example, 4096 colors can be displayed. Note that an organic EL (Electro Luminescence) panel or the like may be employed instead of the liquid crystal panel.

  The communication unit 20 includes an antenna 21 and receives various data such as a game control program from the server in addition to incoming and outgoing line control and transmission / reception of voice data via a wireless public line. Specifically, the communication unit 20 spreads the transmission target data generated by the control unit 40 using, for example, CDMA (Code Division Multiple Access) or the like, and then performs QAM (Quadrature Amplitude phase Modulation), PSK (Phase Shift). Keying), QPSK (Quadrature Phase Shift Keying), and the like to perform transmission processing, and after demodulating the received data, perform despreading processing and output the obtained data to the control unit 40.

  The audio output unit 30 is configured by a piezoelectric speaker or the like, and outputs a call voice during a call, and outputs game music, sound effects, and the like when the game is executed.

  The control unit 40 includes a CPU (Central Processing Unit) that executes arithmetic processing, a ROM (Read-Only Memory) that stores a basic program for operating the mobile phone, and a RAM (Random Access) that temporarily stores data. Memory) or the like.

  The control unit 40 includes a reception unit 41, a determination unit 42, a display control unit 43, a trajectory length calculation unit 44, a movement distance calculation unit 45, a movement unit 46, and a timer unit 47. Note that these functions are realized by the CPU executing a basic program stored in the ROM and a game control program stored in the game control program storage unit 52. In FIG. 1, only blocks representing functions related to the present invention are illustrated, and other blocks are not illustrated.

  The receiving unit 41 receives an operation input from a player that repeatedly moves (traces) a predetermined trajectory with a finger. In the swimming game of the present embodiment, the player can cause the character to swim in the game space using any one of crawl, breaststroke, and butterfly.

  Therefore, there are a crawl trajectory, a breaststroke trajectory, and a butterfly trajectory.

  FIG. 2 is a diagram illustrating the movement of the player's finger during crawling. In the crawl, the player advances the character toward the goal by alternately performing an operation of moving the left and right fingers (for example, the thumb) in contact with the operation display unit 10 from top to bottom.

  In FIG. 2, the upward direction indicates the traveling direction of the character CA and indicates the back side of the player holding the mobile phone. Further, the downward direction indicates the front side of the player. Further, the left direction indicates the left side when viewed from the player holding the mobile phone. The right direction indicates the right side when viewed from the player holding the mobile phone.

  Specifically, first, the player makes one of the left and right fingers contact an arbitrary position P1 of the operation display unit 10, and the touched finger is directed toward the player's near side (from the upper side to the lower side). Move to contact.

  Next, the finger moved to the near side is moved away from the arbitrary position P2 of the operation display unit 10, is again brought into contact with the vicinity of the position P1, and the finger is returned to the original position. The player repeats this operation alternately left and right.

  Therefore, the crawl trajectory includes a pair of left and right left trajectories and a right trajectory, and each of the left trajectory and the right trajectory is a line segment.

  FIG. 3 is a diagram showing the movement of the player's finger during a breaststroke. In FIG. 3, the directions of up, down, left, and right are the same as those in FIG. In the breaststroke, the player moves the character toward the goal by moving the left and right fingers in contact with the operation display unit 10 so as to repeatedly follow a substantially half-moon-like trajectory.

  Specifically, the player first brings the left and right fingers into contact with the arbitrary positions P1 and P1 of the operation display unit 10 almost simultaneously. Next, the player touches and moves the left and right fingers toward the front side so that the left and right fingers touched draw an arc outward. In other words, the player touches the left and right fingers so that the outer circumference of the arc that is swollen to the left is traced with the left finger while the outer circumference of the arc that is swollen to the right is traced with the right finger while the outer circumference of the arc is swollen to the front Move.

  Next, when the left and right fingers touched and moved reach positions P2 and P2, which are arbitrary positions on the operation display unit 10, almost right below the positions P1 and P1, the left and right fingers are moved to the position P2. , P2 from the P2 toward the positions P1 and P1 are moved in a linear manner.

  Next, when the left and right fingers reach the vicinity of the positions P1 and P1, the player again moves the left and right fingers so that the left and right fingers arc outward. The player repeatedly executes this operation.

  Therefore, the trajectory in breaststroke includes a pair of left and right left trajectories and a right trajectory, and the left trajectory includes a line segment L1 and an arc L2 that swells to the left side so as to connect both ends of the line segment L1. Includes a line segment L3 and an arc L4 bulging to the right so as to connect both ends of the line segment L3.

  FIG. 4 is a diagram illustrating the movement of the player's finger in the butterfly. In FIG. 4, the upward, downward, left, and right directions are the same as those in FIGS. In the butterfly, the player moves the character forward by moving the left and right fingers in contact with the operation display unit 10 so as to repeatedly trace the linear trajectory from the upper side to the lower side.

  Specifically, the player first brings the left and right fingers into contact with the arbitrary positions P1 and P1 of the operation display unit 10 almost simultaneously. Next, the player touches and moves the left and right fingers in a straight line toward the near side almost simultaneously.

  Next, when the left and right fingers touched and moved reach positions P2 and P2, which are arbitrary positions on the operation display unit 10, almost right below the positions P1 and P1, the left and right fingers are moved to the position P2. , P2 and again in the vicinity of positions P1 and P1. Next, the player again moves the contacted left and right fingers in a straight line toward the near side. The player repeatedly executes this operation.

  Therefore, the trajectory in the butterfly includes a pair of left and right left trajectories and a right trajectory, and the left trajectory and the right trajectory are line segments having the same length.

  Returning to FIG. 1, when the operation unit for moving the left finger in contact on the display screen and the operation input for moving the right finger on the display screen are alternately received by the receiving unit 41, the determination unit 42 It is determined that the character is swimming in the crawl.

  In addition, the determination unit 42 determines that the player is swimming a character in a breaststroke when an operation input in which the left finger and the right finger are moved in contact with each other so as not to leave the display screen is received by the reception unit 41. .

  In addition, the determination unit 42 determines that the left finger and the right finger are separated from the display screen almost simultaneously (left and right fingers are displaced within a predetermined time) and then substantially simultaneously (the left and right fingers are displaced within a predetermined time). When the operation input touching the display screen is received by the receiving unit 41, the player determines that the character is swimming in the butterfly.

  The display control unit 43 reads the image data of the swimmer character from the image data storage unit 51 and displays it on the operation display unit 10, and changes the character display mode based on the operation input received by the reception unit 41. .

  Specifically, as shown in FIGS. 2 to 4, the display control unit 43 is linked to the operation of the player tracing the trajectory once, and the left arm LA, right arm RA, left leg LF, and right leg of the character CA. The display mode of the character CA is changed so that at least one of the RFs operates.

  More specifically, the display control unit 43 moves the character in a predetermined crawl motion display pattern when the determination unit 42 determines that the player is swimming the character in a crawl.

  Here, for example, the crawl operation display pattern is as follows. As shown in FIG. 2, while the player's right finger moves from the position P1 to the position P2, the display control unit 43 displays the character CA's right arm RA so as to scratch the water from the front toward the rear.

  Further, when the player's right finger is moved away from the position P2, the display control unit 43 turns the right arm RA of the character CA out of the water and rotates it forward, enters the water, and then moves forward. Display to stretch.

  The display control unit 43 also causes the operation display unit 10 to display the left arm LA of the character CA in accordance with the movement of the left finger of the player in the same manner as in the case of the right arm RA.

  In the present embodiment, in the crawl, it takes one stroke from the state in which the right arm RA of the character CA is extended to the return to the original extended state, and one cycle from the state in which the left arm LA of the character CA is extended. Then, it is one stroke until it returns to the original extended state.

  That is, in the crawl, the player performs the operation shown in FIG. 2 by bringing the right finger into contact with the operation display unit 10, and the stroke until the player makes contact with the operation display unit 10 again is one stroke. The operation shown in FIG. 2 is performed by contacting the unit 10, and the stroke until the left finger is brought into contact with the operation display unit 10 again is one stroke.

  In addition, the display control unit 43 displays the right leg RF and the left leg LF of the character CA so as to perform the butterfly movement in conjunction with the actions of the right arm RA and the left arm LA of the character CA.

  Specifically, while the right arm RA of the character CA performs a one-stroke operation, the display control unit 43 alternately performs a butterfly motion of the character CA's left leg LF and right leg RF alternately a predetermined number of times (for example, three times). To display. In addition, while the left arm LA of the character CA performs a one-stroke motion, the display control unit 43 displays the left foot LF and the right leg RF of the character CA alternately so as to perform a butterfly motion a predetermined number of times (for example, three times). To do.

  Further, when the determination unit 42 determines that the player is swimming the character CA in a breaststroke, the display control unit 43 displays the character CA in a predetermined breaststroke action display pattern.

  Here, the operation display pattern of breaststroke is as follows. As shown in FIG. 3, when the left and right fingers of the player are moved in contact with each other so as to draw an arc from the positions P1, P1 to the positions P2, P2, the display control unit 43 displays the left arm LA and the right arm RA of the character CA. Is displayed so as to scratch from the front to the rear.

  At this time, the display control unit 43 displays the left leg LF and the right leg RF of the character CA in a state of extending backward so as to be contracted to the body side.

  Further, when the left and right fingers of the player are linearly moved from the positions P2 and P2 toward the positions P1 and P1, the display control unit 43 extends the left arm LA and the right arm RA of the character CA from the rear to the front. To be displayed.

  At this time, the display control unit 43 displays the left leg LF and the right leg RF of the character CA that is contracted to the body side so as to extend rearward.

  In the present embodiment, in breaststroke, after the left arm LA and the right arm RA of the character CA that is in the forward stretched state perform a scratching operation toward the rear, the operation that returns to the extended state is performed again. Stroke.

  That is, in a breaststroke, it takes one stroke until the player's left and right fingers start contact movement from the positions P1 and P1 and return to the positions P1 and P1 again.

  Further, when the determination unit 42 determines that the player is swimming the character CA by butterfly, the display control unit 43 displays the character CA in a predetermined butterfly motion display pattern.

  Here, the operation pattern of the butterfly is as follows. As shown in FIG. 4, while the left and right fingers of the player are in contact and moving backward from the positions P1 and P1 to the positions P2 and P2, the display control unit 43 moves the character CA in a state of extending forward. The left arm LA and the right arm RA are displayed so as to scratch backward.

  Further, when the left and right fingers of the player move away from the positions P2 and P2, the left arm LA and the right arm RA are taken out of the water, rotated forward to enter, and then displayed to extend forward.

  Here, the display control unit 43 is interlocked with the movement of the character CA until the left arm LA right arm RA comes out of the water and extends forward, and the left leg LF and the right leg RF are centered on both knees with respect to the water surface. After rotating upward, the display is made to rotate downward with respect to the water surface around both knees and kick the water with the left leg LF and the right leg RF.

  In the present embodiment, in the butterfly, after the left arm LA and the right arm RA of the character CA in the state of extending forward perform a scratching operation toward the rear, the operation of returning to the extended state is performed again. Stroke.

  That is, in the butterfly, it takes one stroke until the player's left and right fingers start moving from positions P1 and P1 and return to positions P1 and P1 again.

  Returning to FIG. 1, each time the player performs an operation of tracing the trajectory once based on the operation input accepted by the accepting unit 41, the trajectory length calculating unit 44 actually traces the trajectory of the operation display unit 10. The unit locus length which is the length of is calculated.

  Here, the unit trajectory length includes the left unit trajectory length and the right unit trajectory length, and the trajectory length calculation unit 44 calculates the left unit trajectory length each time the player traces the left trajectory once. Each time the right trajectory is traced once, the right unit trajectory length is calculated.

  Specifically, in the case of crawling, as shown in FIG. 2, the distance that the player actually moved the right finger from position P1 to position P2 is the right unit trajectory length, and the player left from position P1 to position P2. The distance that the finger is actually moved in contact is the left unit trajectory length.

  Then, in the case of crawling, the trajectory length calculation unit 44 determines that the player has traced the left trajectory once when the left finger is released from the operation display unit 10 from the position P2, and ends from the tip of the trajectory of the left finger. Is calculated as the left unit trajectory length. Further, in the case of crawling, the trajectory length calculation unit 44 determines that the player has traced the right trajectory once when the right finger is released from the operation display unit 10 from the position P2, and ends from the tip of the trajectory of the right finger. Is calculated as the right unit trajectory length.

  In the case of a breaststroke, as shown in FIG. 3, the player starts to move the left and right fingers from the positions P1 and P1 until the left and right fingers return to the positions P1 and P1. The distance moved in contact with each other becomes the left unit trajectory length and the right unit trajectory length.

  Specifically, in the case of breaststroke, the trajectory length calculation unit 44 detects the upper bending point corresponding to the position P1 from the acquired trajectories of the left and right fingers, and detects this bending point as the starting point of the trajectory. Then, when the trajectory length calculation unit 44 detects the start points of the left and right trajectories, the trajectory length calculation unit 44 determines that the player has traced the left trajectory and the right trajectory once, and the left and right trajectories from the previous start point of the trajectory to the start point of the trajectory detected this time are determined. Are calculated as a left unit trajectory length and a right unit trajectory length.

  In the case of the butterfly, as shown in FIG. 4, the player actually starts moving the left and right fingers from the positions P1 and P1 until the left and right fingers are released from the operation display unit 10 at the positions P2 and P2. The lengths of the trajectories in which the left and right fingers are moved in contact with each other become the left unit trajectory length and the right unit trajectory length.

  In the case of the butterfly, the trajectory length calculation unit 44 determines that the player has traced the left trajectory and the right trajectory once when the left and right fingers are separated from the operation display unit 10 at the position P2, and the left and right fingers The respective lengths from the front end to the end of the trajectory are calculated as the left unit trajectory length and the right unit trajectory length.

  The trajectory length calculation unit 44 plots the position indicated by the position signal received by the receiving unit 41 in the two-dimensional coordinate space representing each position on the rectangular display screen of the operation display unit 10. The trajectory of the left and right fingers may be acquired.

  In addition, the trajectory length calculation unit 44 obtains, for example, a difference vector between the previously plotted position in the two-dimensional coordinate space and the currently plotted position as needed, and an angle formed between the currently obtained difference vector and the previously obtained difference vector is predetermined. If it is greater than the value of, the previously plotted position may be determined as the inflection point.

  Based on the left unit trajectory length and the right unit trajectory length calculated by the trajectory length calculation unit 44, the movement distance calculation unit 45 calculates a unit movement distance that is a movement distance per action of the character in the game space.

  In this embodiment, since a swimming game is assumed, a movement distance per stroke can be adopted as a movement distance per action.

  In the case of crawling, the moving distance calculation unit 45 calculates a unit moving distance per stroke of the character every time the left unit locus length is calculated by the locus length calculation unit 44, and the locus length calculation unit 44 calculates the right unit locus length. Each time is calculated, the unit movement distance per stroke of the character is calculated.

  Specifically, in the case of crawl, the movement distance calculation unit 45 performs a predetermined crawl for each of the left unit trajectory length LL and the right unit trajectory length RL calculated by the trajectory length calculation unit 44. By multiplying the movement coefficient α1, a unit movement distance TL (= LL · α1, = RL · α1) is calculated.

  In the case of breaststroke and butterfly, the trajectory length calculation unit 44 calculates the left unit trajectory length LL and the right unit trajectory length RL at substantially the same timing, so the moving distance calculation unit 45 calculates the left unit trajectory length LL and the right unit trajectory. The unit movement distance TL is calculated every time both the trajectory length RL is calculated.

  Specifically, in the case of breaststroke and butterfly, the movement distance calculation unit 45 obtains a representative value PL of the left unit trajectory length LL and the right unit trajectory length RL calculated by the trajectory length calculation unit 44, and this representative value PL Is multiplied by a predetermined breaststroke movement coefficient β1 and a butterfly movement coefficient γ1 to calculate a unit movement distance TL (= PL · β1, PL · γ1). As the representative value PL, for example, an average value (= (LL + RL) / 2, = √ (LL · RL)) of the left unit trajectory length LL and the right unit trajectory length RL may be employed, or the sum ( = LL + RL) may be adopted.

  In addition, as the movement coefficient α1 for crawl, the movement coefficient β1 for breaststroke, and the movement coefficient γ1 for butterfly, for example, the unit locus length calculated by the locus length calculation unit 44 is a predetermined standard length. In addition, a value that is a distance between a crawl, a breaststroke, and a butterfly that a general swimmer can proceed in one stroke may be adopted.

  Further, the movement distance calculation unit 45 calculates a distance decrease value DL that increases as the difference between the left unit locus length LL and the right unit locus length RL increases, and calculates the distance decrease value DL from the unit movement distance TL. By subtracting, the unit moving distance TL is corrected.

  In this case, for example, the movement distance calculation unit 45 determines a predetermined reduction coefficient (a reduction coefficient α2 for crawl, a reduction coefficient β2 for breaststroke) with respect to the absolute value of the difference between the left unit locus length LL and the right unit locus length RL. The distance reduction value DL (= | LL−RL | · α2, = | LL−RL | · β2, = | LL−RL | · γ2) may be calculated by multiplying by the butterfly reduction coefficient γ2). .

  In addition, when | LL−RL | is smaller than the threshold value TH1, the movement distance calculation unit 45 may not calculate the distance decrease value DL and do not correct the unit movement distance TL. Thereby, the difficulty of a game can be made low.

  When an actual human swims in the water, if the force of scratching the water with the left arm LA is greater than the force of scratching the water with the right arm RA, the direction of travel is relative to the reference direction which is the direction of the straight line connecting the start point to the goal point. Tilt to the right.

  In addition, when the force of scratching the water with the right arm RA is greater than the force of scraping the water with the left arm LA, the actual person inclines the traveling direction to the left with respect to the reference direction.

  Therefore, the movement distance calculation unit 45 calculates the distance decrease value DL that increases as the difference between the left unit locus length LL and the right unit locus length RL increases, and calculates the distance decrease value DL from the unit movement distance TL. By subtracting and correcting the unit movement distance TL, the movement distance in the reference direction is reduced due to a shift in the traveling direction with respect to the reference direction that occurs in accordance with the difference in force when the water of the left arm LA and the right arm RA is scratched. Can be reproduced.

  Specifically, in the case of crawling, the movement distance calculation unit 45 calculates the unit movement distance TL each time the left unit locus length LL is calculated, and unit movement distance every time the right unit locus length RL is calculated. TL is calculated, and the absolute value of the difference between the current left unit trajectory length LL and the previous right unit trajectory length RL (= | LL−RL | or the current right unit trajectory length RL and the previous left unit trajectory length LL As the absolute value (= | RL−LL |) of the difference between the values increases, the distance decrease value DL is calculated so as to increase, and the distance decrease value DL is subtracted from the current unit movement distance TL to thereby decrease the current unit. The movement distance TL (= TL-DL) is corrected.

  Further, in the case of a breaststroke, the movement distance calculation unit 45 is configured so that the unit movement distance TL decreases when the shape of the trajectory of the left and right fingers that the player actually traces the operation display unit 10 deviates from the shape of the breaststroke trajectory. The unit moving distance TL is corrected.

  FIG. 5 is an explanatory diagram of a process for determining whether or not the shape of the trajectory of the left and right fingers actually traced by the player on the operation display unit 10 is deviated from the shape of the trawl of the breaststroke.

  As shown in FIG. 5, the movement distance calculation unit 45 detects finger positions P1, P1 (arc start points) on the operation display unit 10 when the player starts the operation of tracing the arcs L2, L4 shown in FIG. Then, arc determination points PH1 and PH2 are set at predetermined positions on the display screen of the operation display unit 10 with the positions P1 and P1 as a reference, and the trajectories K2 and K4 of the arcs L2 and L4 traced by the player are the arc determination points PH1. , PH2 determines that the shape of the trajectories K2, K4 is not deviated from the shape of the breaststroke trajectory.

  That is, the movement distance calculation unit 45 shifts the shapes of the trajectories K2 and K4 from the shape of the breaststroke trajectory when the trajectory K2 passes the left side of the arc determination point PH1 and the trajectory K4 passes the right side of the arc determination point PH2. Judge that it is not.

  On the other hand, when the trajectories K2 and K4 pass inside the arc determination points PH1 and PH2, the moving distance calculation unit 45 determines that the shapes of the trajectories K2 and K4 are shifted from the breaststroke trajectory.

  That is, when the trajectory K2 passes the right side of the arc determination point PH1 and the trajectory K4 passes the left side of the arc determination point PH2, the movement distance calculation unit 45 deviates from the shape of the breaststroke trajectory. It is determined that

  Here, when it is determined that the trajectories K2 and K4 are deviated from the shape of the breaststroke trajectory, the movement distance calculation unit 45 corrects the unit movement distance TL by subtracting a predetermined value from the unit movement distance TL. Alternatively, the deviation of the trajectories K2 and K4 with respect to the shape of the breaststroke trajectory may be obtained, and the value subtracted from the unit movement distance TL may be increased as the deviation increases.

  In this case, when the movement distance calculation unit 45 determines that the trajectory K2 is deviated from the shape of the breaststroke trajectory, the movement distance calculation unit 45 obtains the shortest distance d1 between the trajectory K2 and the arc determination point PH1, and reduces the decrease coefficient β2 to the shortest distance d1. The unit movement distance TL (= TL−d1 · β2) may be corrected by obtaining a value (= d1 · β2) multiplied by and subtracting this value from the unit movement distance TL.

  In addition, as the position of the arc determination point PH1, for example, a line segment L1 of the left orbit is drawn downward from the position P1 on the left side, and the direction perpendicular to the line segment L1 from the midpoint PM1 of the line segment L1, A position separated by a predetermined distance can be employed on the left side of the midpoint PM1.

  Further, as the position of the arc determination point PH2, for example, the line segment L3 of the right trajectory is drawn downward from the right position P1, and the middle of the line segment L3 is perpendicular to the line segment L3 from the middle point PM2. A position separated by a predetermined distance can be adopted on the right side of the point PM2.

  When the movement distance calculation unit 45 determines that the locus K4 is deviated from the shape of the breaststroke track, the movement distance calculation unit 45 obtains the shortest distance d2 between the locus K4 and the arc determination point PH2, and sets the decrease coefficient β2 to the shortest distance d2. A multiplied value (= d2 · β2) is obtained, and this value may be subtracted from the unit movement distance TL (= TL−d2 · β2).

  The movement distance calculation unit 45 determines that the player's operation is deviated from the breaststroke trajectory when at least one of the trajectories K2 and K4 does not pass outside the arc determination points PH1 and PH2. Alternatively, if both the trajectories K2 and K4 do not pass outside the arc determination points PH1 and PH2, it may be determined that the player's operation is deviated from the breaststroke trajectory.

  Note that the process illustrated in FIG. 5 is an example, and another process may be employed. In this case, for example, when the lengths of the trajectories K2 and K4 are shorter than the lengths of the arcs L2 and L4, it may be determined that the trajectories K2 and K4 are deviated from the shape of the breaststroke trajectory. Further, the cross-correlation value between the shapes of the trajectories K2, K4 and the shapes of the arcs L2, L4 is obtained by pattern recognition, and the deviation of the shape of the trajectories K2, K4 from the shape of the breaststroke trajectory is obtained according to the cross-correlation values. good.

  In the case of a butterfly, the movement distance calculation unit 45 returns the timing at which the left finger returns to the tip of the line segment that becomes the left orbit and touches the display screen of the operation display unit 10, and the line that the right finger makes the right orbit. The unit movement distance is corrected so that the unit movement distance TL is reduced when the timing of returning to the tip of the minute and the timing of contacting the display screen of the operation display unit 10 deviate.

  Here, the moving distance calculation unit 45 has a predetermined absolute value of the difference between the timing at which the left finger contacts the display screen of the operation display unit 10 and the timing at which the right finger contacts the display screen of the operation display unit 10. If the threshold value TH2 is greater than or equal to TH2, it is determined that both timings are shifted. However, the movement distance calculation unit 45 is not limited to this, and the timing at which the left finger contacts the display screen of the operation display unit 10 and the timing at which the right finger contacts the display screen of the operation display unit 10 are slightly different. However, when they are shifted, it may be determined that both timings are shifted.

  When the movement distance calculation unit 45 determines that both timings are shifted, the movement distance calculation unit 45 corrects the unit movement distance TL by subtracting a predetermined value from the unit movement distance TL.

  However, the present invention is not limited to this, and the movement distance calculation unit 45 may dynamically change the value to be subtracted from the unit movement distance TL according to the difference between both timings. In this case, the movement distance calculation unit 45 measures the difference time DT of both timings, obtains a value (= DT · γ2) obtained by multiplying the difference time DT by a predetermined coefficient γ2, and calculates this value from the unit movement distance TL. The unit movement distance TL (= TL−γ2 · D2) may be corrected by subtracting (D2 · γ2).

  When the absolute value (= | LL−RL |) of the difference between the left unit trajectory length LL and the right unit trajectory length RL is greater than a predetermined threshold value TH3, the display control unit 43 determines that the left unit trajectory length LL is equal to the right unit trajectory length LL. When the length is shorter than the length RL, the character CA is tilted to the left from the reference direction, and when the right unit trajectory length RL is shorter than the left unit trajectory length LL, the character CA is tilted to the right from the reference direction. At this time, the display control unit 43 may display an afterimage of the character CA in the reference direction.

  Thereby, the player can recognize that the character cannot move forward efficiently in the game space because the balance of the movement of the left and right fingers is poor.

  The moving unit 46 moves the character CA along the reference direction by the unit moving distance TL in the game space every time the unit moving distance TL is calculated by the moving distance calculating unit 45.

  FIG. 6 is a schematic diagram showing the moving character CA in the game space. Here, for example, a virtual two-dimensional space can be employed as the game space. A start point SP and a goal point GP are set at predetermined positions in the game space. A line segment along the reference direction connecting the start point SP and the goal point GP virtually represents one lane of the actual pool.

  Accordingly, the moving unit 46 regards the character CA as, for example, a mass point that moves along a line segment along the reference direction, obtains an integrated value of the unit moving distance TL by the moving distance calculating unit 45, and this integrated value is the length of the line segment. If it is equal to or greater than Z1, it may be determined that the character CA has reached the goal point GP.

  The timer 47 measures the time until the character CA reaches the goal point GP from the start point SP, and calculates the time as the player's score.

  Therefore, the player can know that the shorter this time is, the better the game results are. In addition, when the same game as the opponent is played, it is possible to determine a win or a loss by comparing which time is shorter.

  Returning to FIG. 1, the storage unit 50 includes a non-volatile rewritable storage device such as an EEPROM, and includes an image data storage unit 51 and a game control program storage unit 52.

  The image data storage unit 51 stores image data of a character CA who is a swimmer, background image data of a pool in which the character CA swims, and the like.

  The game control program storage unit 52 stores a game control program that causes the mobile phone to function as a game device.

  FIG. 7 is a flowchart showing the operation of the mobile phone when the mobile phone shown in FIG. 1 functions as a game device. First, when the player instructs the start of the game in step S1 (YES in step S1), the display control unit 43 displays the image data of the character CA, the image data of the background of the character CA, and the like in the image data storage unit 51. And is displayed on the operation display unit 10 (step S2).

  Note that the player may start the game by touching a game start button displayed on the operation display unit 10, for example.

  Next, an operation input for tracing the crawl, breaststroke, or butterfly trajectory is performed on the display screen of the operation display unit 10 by the player, and the receiving unit 41 receives an operation input from the player (step S3).

  Next, the determination unit 42 determines which operation input has been performed by the player, such as crawl, breaststroke, and butterfly (step S4). In this case, the determination unit 42 may prevent the character CA from moving forward until the player can recognize which of the crawl, breaststroke, and butterfly tracks. The details of the determination process of the determination unit 42 have been described above.

  Next, when the determination part 42 determines with a crawl (A in step S4), a crawl process is started (step S5). Moreover, when the determination part 42 determines with a breaststroke (B in step S4), a breaststroke process is started (step S6). Further, when the determination unit 42 determines that it is a butterfly (C in step S4), butterfly processing is started (step S7).

  FIG. 8 is a flowchart showing details of the crawl process. First, when the reception unit 41 detects that one of the left and right fingers of the player has touched the display screen of the operation display unit 10 (YES in step S11), the trajectory length calculation unit 44 is operated by the player. A trajectory actually traced on the display screen of the display unit 10 is acquired (step S12).

  Here, when the finger touches the area on the right side with respect to the center line CHL of the character shown in FIG. 2 displayed on the operation display unit 10, the reception unit 41 determines that the touched finger is the right finger, and the center line When a finger touches the region on the left side with respect to CHL, the touched finger is determined as the left finger. This determination is the same for breaststroke and butterfly.

  Next, when the reception unit 41 detects that the player's finger has left the display screen of the operation display unit 10 (YES in step S13), the trajectory length calculation unit 44 determines the left unit trajectory length LL or the right unit. The trajectory length RL is calculated (step S14).

  Here, the trajectory length calculation unit 44 calculates the left unit trajectory length LL from the trajectory of the left finger acquired in step S12 when the receiving unit 41 determines that the left finger has moved away from the operation display unit 10, and the right finger Is determined to be away from the operation display unit 10, the right unit trajectory length RL is calculated from the trajectory of the right finger acquired in step S12.

  On the other hand, when the reception unit 41 does not detect that the left finger or the right finger is separated from the operation display unit 10 (YES in step S13), the process returns to step S12, and the trajectory length calculation unit 44 Continue to acquire the trajectory of the right finger.

  In step S15, the movement distance calculation unit 45 calculates a unit movement distance TL from the left unit locus length LL or the right unit locus length RL (step S15). Here, when the left unit locus length LL is calculated in step S14, the movement distance calculation unit 45 multiplies the left unit locus length LL by the crawl movement coefficient α1 to obtain the unit movement distance TL (= LL · α1). What is necessary is just to calculate.

  On the other hand, when the right unit locus length RL is calculated in step S14, the movement distance calculation unit 45 multiplies the right unit locus length RL by the crawl movement coefficient α1 to calculate the unit movement distance TL (= RL · α1). That's fine.

  Next, the movement distance calculation unit 45 obtains the absolute value (= | LL−RL |) of the difference between the left unit trajectory length LL and the right unit trajectory length RL, and when the absolute value of this difference is equal to or greater than the threshold value TH1, It is determined that the balance between the movements of the left and right fingers of the player is bad (YES in step S16), and the process proceeds to step S17.

  Next, the travel distance calculation unit 45 obtains a distance decrease value DL by | LL−RL | · α2, subtracts the distance decrease value DL from the unit travel distance TL calculated in step S15, and corrects the unit travel distance TL ( Step S17).

  On the other hand, when | LL−RL | is smaller than the threshold value TH1, the moving distance calculation unit 45 determines that the balance of the movement of the left and right fingers of the player is good (NO in step S16), and performs the process through step S17. Proceed to step S18.

  Next, in step S18, when | LL-RL | is equal to or greater than the threshold value TH3, the display control unit 43 determines that it is necessary to notify the player that the balance between the movements of the left and right fingers is bad (in step S18). YES), the process proceeds to step S19.

  Next, the display control unit 43 uses the operation display unit 10 to notify that the balance between the movements of the left and right fingers of the player is bad (step S19). FIG. 9 is a diagram illustrating an example of an image displayed on the operation display unit 10 when the balance between the movements of the left and right fingers of the player is poor.

  In FIG. 9, since the left unit trajectory length LL is shorter than the right unit trajectory length RL, the character CA is displayed tilted to the left (counterclockwise) by an angle θ with respect to the reference direction. Further, an afterimage ZZ of the character CA is displayed so that the center line CHL is parallel to the reference direction. Here, the character CA and the afterimage ZZ may be displayed in different colors, or may be displayed so that the luminance of the afterimage ZZ is lower than the luminance of the character CA. This notification may be canceled when the left unit trajectory length LL and the right unit trajectory length RL become the same by the finger operation continuously performed by the player thereafter.

  On the other hand, if | LL-RL | is smaller than the predetermined threshold TH3 in step S18, the display control unit 43 determines that there is no need to notify (NO in step S18), and passes through the process in step S19. The process proceeds to step S20.

  Next, the moving unit 46 accumulates the unit moving distance TL and advances the character CA in the game space (step S20).

  Next, the moving part 46 complete | finishes a process, when it determines with the character CA having reached | attained the goal point GP (it is YES at step S21). On the other hand, when the moving unit 46 determines that the character CA has not reached the goal point GP (NO in step S21), the moving unit 46 returns the process to step S11.

  FIG. 10 is a flowchart showing details of the breaststroke process of FIG. First, in step S31, the trajectory length calculation unit 44 acquires a trajectory that the player actually traces on the display screen of the operation display unit 10 (step S31).

  Next, when the trajectory length calculation unit 44 detects the positions P1 and P1 from the acquired trajectory (YES in step S32), the arc determination points PH1 and PH2 are set as shown in FIG. 5 (step S33).

  Here, the trajectory length calculation unit 44 may set the arc determination point PH1 when detecting the left position P1, and may set the arc determination point PH2 when detecting the right position P1.

  On the other hand, when the positions P1 and P1 are not detected in step S32 (NO in step S32), the trajectory length calculation unit 44 returns the process to step S31 and continues acquiring the trajectory.

  In step S34, the trajectory length calculation unit 44 acquires a trajectory in the same manner as in step S31.

  Next, the trajectory length calculation unit 44 determines that the operation of tracing the left trajectory once has been completed by detecting the position P1 that is the upper bending point of the left finger trajectory, and the upper bending of the right finger trajectory. By detecting the position P1, which is a point, it is determined whether or not the operation of tracing the right orbit is completed (step S35), and it is determined that the operation of tracing both the left and right tracks is completed. If so (YES in step S35), the left unit trajectory length LL and the right unit trajectory length RL are calculated (step S36).

  Specifically, the trajectory length calculation unit 44 calculates the left unit trajectory length LL by calculating the length of the trajectory of the left finger connecting the left position P1 detected this time and the left position P1 detected last time. At the same time, the right unit trajectory length RL is calculated by calculating the length of the trajectory of the right finger connecting the right position P1 detected this time and the right position P1 detected last time.

  Next, the movement distance calculation unit 45 obtains an average value of the left unit locus length LL and the right unit locus length RL as a representative value PL, and calculates a unit movement distance TL by TL = PL · β1 (step S37).

  Next, as in step S16 of FIG. 8, by comparing | LL−RL | with the threshold value TH1, it is determined whether or not the balance of movement of the left and right fingers is bad (step S38). If it is determined that the movement balance is poor (YES in step S38), the process proceeds to step S39.

  Next, the movement distance calculation unit 45 obtains a distance decrease value DL by | LL−RL | · β2, subtracts the distance decrease value DL from the unit movement distance TL calculated in step S37, and obtains a unit movement distance TL (= TL−). DL) is corrected (step S39).

  On the other hand, when the movement distance calculation unit 45 determines that the balance between the movements of the left and right fingers is not bad (NO in step S38), the process proceeds to step S40 through step S39.

  Next, as in step S18 shown in FIG. 8, the display control unit 43 needs to notify the player that the balance between the movements of the left and right fingers is bad by comparing | LL-RL | and the threshold value TH3. It is determined whether or not there is (step S40).

  If the display control unit 43 determines that it is necessary to notify the player that the balance between the movements of the left and right fingers is bad (YES in step S40), the display control unit 43 uses the operation display unit 10 to move the left and right fingers. Is informed to the player (step S41).

  On the other hand, if the display control unit 43 determines that it is not necessary to notify the player that the balance between the movements of the left and right fingers is not good (NO in step S40), the process proceeds to step S42 through step S41. .

  In step S42, as shown in FIG. 5, when the trajectories K2 and K4 traced by the player pass inside the arc determination points PH1 and PH2, the movement distance calculation unit 45 makes the trajectories K2 and K4 have a breaststroke trajectory. (Step S42: YES), the unit movement distance TL is corrected (step S43).

  On the other hand, in step S42, when the trajectories K2, K4 pass outside the arc determination points PH1, PH2, the travel distance calculation unit 45 determines that the shapes of the trajectories K2, K4 are not deviated from the shape of the breaststroke trajectory. (NO in step S42), through step S43, the process proceeds to step S44.

  The processing in steps S44 and S45 is the same as steps S20 and S21 in FIG.

  FIG. 11 is a flowchart showing details of the butterfly process shown in FIG. First, when the reception unit 41 detects that the left and right fingers of the player have touched the display screen of the operation display unit 10 (YES in step S51), the trajectory length calculation unit 44 causes the player to display the operation display unit 10. Each of the trajectory of the left finger and the trajectory of the right finger that actually traces on the screen is acquired (step S52).

  Next, when the reception unit 41 detects that the left and right fingers of the player have left the display screen of the operation display unit 10 (YES in step S53), the trajectory length calculation unit 44 determines whether the left unit trajectory length LL or The right unit trajectory length RL is calculated (step S54).

  Here, the trajectory length calculation unit 44 calculates the left unit trajectory length LL when the left finger leaves the display screen of the operation display unit 10, and when the right finger leaves the display screen of the operation display unit 10. The right unit trajectory length RL may be calculated.

  Next, the movement distance calculation unit 45 obtains a representative value PL of the left unit locus length LL and the right unit locus length RL, and multiplies the representative value PL by a butterfly movement coefficient γ1 to obtain a unit movement distance TL (= PL · γ1). ) Is calculated (step S55).

  In steps S56 and S57, the movement distance calculation unit 45 corrects the unit movement distance TL when the balance between the movements of the left and right fingers is poor, in the same manner as the processes in steps S38 and S39 in FIG.

  In step S58, the movement distance calculation unit 45 returns the timing at which the left finger returns to the tip of the line segment that becomes the left trajectory and contacts the display screen of the operation display unit 10, and the line segment that makes the right finger the right trajectory. The timing TIM2 that is returned to the tip of the operation display unit 10 and touches the display screen of the operation display unit 10 is detected. If | TM1-TM2 | is equal to or greater than the threshold value TH2, it is determined that the timing TIM1 is deviated from the timing TM1 ( In step S58, YES), the process proceeds to step S59.

  Next, the movement distance calculation unit 45 corrects the unit movement distance by subtracting a predetermined value from the unit movement distance TL (step S59).

  Next, in steps S60 and 61, the display control unit 43 determines whether or not the balance of the movement of the left and right fingers of the player is bad, as in steps S40 and S41 shown in FIG. Notifies the user using the operation display unit 10 as in the case of crawling.

  Next, in steps S62 and S63, the moving unit 46 moves the character until reaching the goal point GP in the same manner as in steps S44 and S45 shown in FIG.

  On the other hand, if | TIM1-TIM2 | is less than the threshold value TH2, the moving distance calculation unit 45 determines that the timing TIM1 and the timing TIM2 are not shifted (NO in step S58), and passes through step S59 to perform the process. Proceed to S60.

  As described above, according to the game device according to the present embodiment, when the player performs an operation of repeatedly tracing the crawl, breaststroke or butterfly trajectory, the character display mode displayed on the operation display unit 10 according to the operation. Changes. Further, each time the player performs an operation of tracing the crawl, breaststroke or butterfly trajectory once, the left unit trajectory length LL which is the length of the trajectory actually traced by the player with the left and right fingers, and the right unit trajectory length LL. A unit locus length RL is calculated.

  Then, based on the calculated left unit trajectory length LL and right unit trajectory length RL, a unit movement distance TL that is a movement distance per character stroke in the game space is calculated. Then, the character CA is moved by the unit movement distance TL in the game space.

  That is, as the number of times the player traces the predetermined trajectory increases, the number of times the unit moving distance TL is calculated increases, and the moving speed of the character CA can be increased accordingly.

  On the other hand, the player increases the left unit trajectory length LL and the right unit trajectory length RL when the crawl, breaststroke, or butterfly trajectory is traced once, that is, the distance by which the finger touches the operation display unit 10. The longer the unit moving distance TL is, the longer the character CA is moved.

  Therefore, the player is required to make the distance per track around which the finger is moved in contact as long as possible, and at the same time, increase the number of times the track is traced.

  Thereby, a character can be moved by performing an operation of repeatedly tracing the operation display unit 10 with a finger, and a game for moving the character is realized by utilizing a user interface of a portable terminal having a touch panel type display unit. be able to.

  In the above embodiment, one character CA is displayed on the operation display unit 10 and the time for moving from the start point SP to the goal point GP by the character CA is shown. However, the present invention is not limited to this. Not.

  That is, two characters CA are displayed on the operation display unit 10, one character CA is automatically moved by the control of the control unit 40, and the other character CA is moved by an operation by the player. A mode in which the character CA moved by 40 and the character CA moved by the player's operation may be competed.

  Further, the player may arbitrarily select the distance from the start point SP to the goal point GP. For example, before starting the game, the player can select the distance from the start point SP to the goal point GP such as 50 m, 100 m, 200 m, 500 m, 1 km, and the character CA can swim the distance selected by the player May be adopted.

  In the above-described embodiment, the determination unit 42 determines the type of swimming of the character CA from the player's operation immediately after the start of the character CA, and adopts an aspect in which the character CA can swim with the determined type of swimming. It is not limited.

  That is, before starting the game, the player may select the type of swimming and may adopt a mode in which the character CA can swim according to the swimming method selected by the player.

  Moreover, although the swimming game was illustrated in the said embodiment, this invention is not limited to this. For example, any game that competes for the time required from the start point SP to the goal point GP, such as an athletics game or a speed skating game, can be applied.

  As an athletics game, for example, a 100m run, a 200m run, etc., and a track competition are mentioned. In the case of the above-described swimming game, the arms of the character CA are moved alternately or simultaneously in conjunction with the movement of the finger of the player. In the case of these track and field games, the legs of the character CA are moved alternately. What is necessary is just to make it the structure which performs operation. It can also be applied to obstacle races such as 100m hurdles and 200m hurdles. In this case, if the player performs the above-described crawl, breaststroke, or butterfly operation and adopts a display mode in which the character CA automatically jumps over the obstacle when the character CA reaches before the obstacle. Good. The speed skating game and the aspect may be the same as the above-described track and field games.
